What’s been discovered inside it?
In the 1960’s, a group of cave explorers from Austin, Texas, got the idea that the state of Oaxaca was the right place to search for that really deep cave they had long dreamed of finding.
They had been studying the mountainous areas of Mexico for some time, looking for just the right combination of factors: thick limestone, lots of annual rainfall and a lack of surface streams, which would indicate subterranean drainage.
Once they pinpointed Oaxaca’s Huautla area, which sees 100 inches of rainfall every year, they acquired stereo aerial photos and spotted large cave entrances with visible streams flowing into them. They also noted that there was a newly constructed road into the area.
The stage was set for a major discovery.
